Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

readOnlyHint=true already tells the agent this is a safe read, so the bar is lower. The description adds the GET endpoint and the filterable behavior, but says nothing about pagination semantics (next_token/page_size) or result ordering, which matters for a list tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence carrying the purpose and filters, followed by an endpoint reference. The endpoint string is mildly redundant but useful for API-aware agents, and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description does not need to explain return values, and it is a read-only list with full schema coverage. It is complete for correct invocation, with pagination behavior the only meaningful omission.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter including sort, roles, permissions, page_size and next_token is already documented in the schema. The description only echoes the two filter parameters, adding no syntax or format detail beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb (list) and resource (users of one organization) and scopes it to a single org, which naturally separates it from the sibling kinde_list_users. It does not explicitly name the sibling it differs from, so it stops just short of full differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states the optional filtering dimensions (permissions, roles), which implies when the tool is useful, but gives no explicit when-to-use/when-not guidance or alternatives such as kinde_get_user_roles_in_organization for per-user lookups. Usage is inferable rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
